Zusammenfassung:	The present invention provides a sealing device in which frictional resistance is further reduced while a sealing property is maintained. In a section passing through a central axis of the annular sealing device 100, if a radius of curvature of a curved face between a first inclined face 110X and a second inclined face 110Y is R0, a radius of curvature of a curved face between a side face on a sealed fluid side (O) and the first inclined face 110X in an annular groove is R1a, R2a, R3a, and R4a for respective annular grooves, and a radius of curvature of a curved face between a side face on an atmosphere side (A) and the first inclined face 110X in an annular groove is R1b, R2b, R3b, and R4b for the respective annular grooves, R1b, R2b, R3b, R4b < R0 < R1a, R2a, R3a, R4a is satisfied.
